' COLLAR BUTTON WITH DETACHABLE HEAD Filed Feb. 5, 1937 Patented Sept. 13, 1938 UNITED STATES ATENT OFFICE Hagbarth Sylvester Christophersen, Odense, Denmark Application February 3, 1937, Serial No. 123,911 In Denmark February 8, 1936 1 Claim.

This invention relates to a collar stud of the ldnd having a detachable separate head, i. e. a head having no secondary function of maintaining the necktie in its proper position and being therefore independent of devices constructed for that purpose.

The object of the invention is to provide an improved construction of collar stud having a detachable separate head which will be convenient and effective.

According to the invention, a collar stud comprises a blade or-plate shaped neck or stem, a slot or slot like hole in the stem disposed near the front end thereof and elongated in the direction of the length of the stem, and a detachable. head consisting of a mainly V-shaped resilient clip of metal wire adapted to be pushed through the slot in a direction transverse to the stem until it occupies a position in which it is held 20 firmly by its own resiliency.

The invention is illustrated in the accompanying drawing, in which:-

Figure 1 shows the button in side elevation, with the button head in position.

Figure 2 a vertical central section of the button head, detached from the button.

Figure 3 the button plate and neck in top View, and

Figures 4, 5 and 6 two modified constructions 30 of the button head.

' In the construction shown in Figures 1-3, is the bottom plate of the button, 2 its blade or plate shaped neck or stem which has a great width in the direction of the button hole, but only 35 a slight thickness at right angles thereto, 3 is a hole through the button neck, long in the longitudinal direction of the same. The button head, which is pressed into the hole of the button neck preferably from above, consists of a resilient, mainly V-shaped, clip made from thin, highly resilient metal wire 4. The two branch ends of the clip may conveniently point upward, when the button is in position, as shown. One branch of the clip is firmly pinched, at the top, in a small flat metal capsule 5, into the cavity of which the other branch of the clip extends freely in. such a manner, that it can move towards and away from the stationary branch of the clip, but cannot get out of the capsule.

In the construction shown, the movable branch of the clip has a small inward bend 6, closely below the metal capsule 5. This bend which also may be provided on the stationary branch of the clip may be useful for holding the head in position, when the same has been inserted in the button neck, with the metal capsule 5 resting against the upper or lower surface of the button neck. This button head is very easily gripped with two fingers and inserted into or removed from the button neck. It does not matter, whether the stationary or the movable branch of the head is facing the bottom plate of the button.

Figure 4 shows a modified construction of the capsule 5 according to Figure 2 and viewed at right angle thereto. The top of the capsule is here provided with a lateral projection 'l which facilitates the removal of the detachable button head when the head is gripped by two fingers, the nail of one of the same resting against the underside of the said projection.

The metal capsule 5 is a convenience but no necessity. The head may in fact consist solely of a resilient metal wire 8 bent into V-shape, as shown in Figure 5, or it may be shaped as shown in Figure 6, in which the two branches of the resilient clip 8 are crossing one another.

Also other forms of the button head may be imagined, which allow the head to be maintained in position resiliently and securely in the button neck.

Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed, I declare that what I claim is:

A collar stud comprising a base; a plate shaped shank projecting at right angle therefrom and having an elongated slot therein extending from a point adjacent its outer end towards the base; and a detachable head extending through said slot and consisting of a flattened metal capsule of somewhat larger size than the slot, a substantially V-shaped resilient clip having one leg secured at one end of the capsule and the other leg also confined in the capsule, but freely movable towards and away from the first named leg, whereby, when the clip is inserted into the said slot in a direction normal to the plane of the shank the head will be held firmly in the said slot due to the resiliency of the clip.
